This is a problem that shows up when printing to an HP Laserjet 4100N from either an iMac or a TiBook running NWExpress:
You can detect a very slight shading in the printout, in what you might call the "text box," so faint that it doesn't get picked up when making copies but still definitely visible in the original.
Has anyone noticed this occurring with other printers?
So, I suppose that adding "printing problems" I and II together leads to the conclusion that my marginal existence is problematic and slightly shady.
